Embodiment 1

[0039] The anti-blocking electric knife pencil of the present embodiment, as Figure 1-Figure 3 As shown, it includes a cutter head 1, a suction tube 2 and an installation assembly. The cutter head 1 is arranged on the tube wall of the suction tube 2, and the cutter head 1 is suitable for cutting tissue; the installation assembly includes a housing 3, an insulating sleeve 4, an insulating sleeve The tube 4 is sleeved on the suction tube 2, and is arranged between the casing 3 and the cutter head 1, and is suitable for covering the suction tube 2;

[0040] The electric knife pencil of this embodiment also includes an electric control unit 5, a pressing assembly and a liquid inlet interface. The electric control unit 5 is installed on the housing 3 and is in contact with the suction tube 2, and is suitable for controlling the magnitude of the current on the suction tube 2; The assembly includes a conduction hose 6 and a pressing member 7, the pressing member 7 is arranged on the...

Embodiment 2

[0056] The system of this embodiment includes the above-mentioned anti-blocking electric knife pen, and also includes a liquid injection device. After the blockage occurs, connect the liquid injection device to the connector 8 on the liquid inlet interface, and then press the pressing member in Embodiment 1 7. Realize liquid injection while pressing. The connector 8 is made of an elastic material, which covers the infusion tube on the liquid injection device, so that no water leakage occurs during liquid injection.

Abstract

The invention relates to the technical field of medical instruments, in particular to an anti-blocking electric knife pen and a system thereof. The anti-blocking electric knife pen includes a cutter head, a suction tube and an installation assembly, and the cutter head is arranged on the pipe wall of the suction tube; the installation assembly includes a casing and an insulating sleeve, and the insulating sleeve is sleeved on the suction tube and arranged on the casing. between the body and the cutter head; it also includes an electronic control unit, a pressing component and a liquid inlet interface, the electronic control unit is installed on the casing and is in contact with the suction tube, which is suitable for controlling the current on the suction tube; the pressing component includes a conduction A hose and a pressing piece, the pressing piece is arranged on the casing, and one end is connected with the conducting hose, and the pressing piece is suitable for squeezing the conducting hose under the action of external force; the liquid inlet port is arranged on the casing, and the liquid inlet port One end is connected with the suction tube, and the other end is suitable for connection with the liquid injection device. When the external force acts on the pressing member, the liquid injection device injects liquid into the suction tube, realizing liquid injection at the same time of pressing, better cleaning effect and more time-saving Efficient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-blocking electric knife pen and a system thereof. Background technique [0002] High-frequency electrotome (high-frequency surgical device) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency high-voltage current generated by the effective electrode tip contacts the human body, and realizes the separation and coagulation of the tissue, thereby achieving the purpose of cutting and hemostasis. [0003] In the process of using an electrosurgical pen for surgery, it is usually accompanied by cauterization and carbonization of the patient's tissue, as well as the gasification of the patient's body fluid and blood. These high-temperature processes generate large volumes of surgical fumes. [0004] On the one hand, surgical smoke will reduce the clarity of the surgeon's view of the patient'...
